Shallow Water pH Logger AquapHOx-L-pH

Broad range of optical pH sensors
Operation up to 100 m depth
Stand-alone logging up to >1 year
Integrated rechargeable battery
Integrated fast Pt100 temp. sensor

The AquapHOx-L-pH is a pH long-term logger for stand-alone shallow-water operation down to 100m water depth. The logger was designed as platform to be combined with a wide range of different optical pH or temperature sensor formats. The selection of diverse pH sensor formats offers maximum flexibility regarding application like measurements of ocean pH on the total scale with neglectable impact of salinity.

The entire pH sensor portfolio with SUB-connector can be used with the AquapHOx-L-pH logger. Maintenance time is minimized by simply exchanging these disposable sensor heads. Choose between a pH sensor cap (PHCAP-PKx-SUB) for long-time monitoring or fiber-optic screw-cap probes (PHROBSC-PKX-SUB) for pH sensing with spatial resolution in e.g. coral reefs. The pH sensors are also available for different pH ranges suitable for your application.

Simultaneous oxygen monitoring is can be realized by parallel deployment of the AquapHOx-L-O2 logger. For deployments >100m depth, please refer to our deep-sea multi-analyte logger AquapHOx-LX with titanium housing.

POM Housing. This device can be deployed to a depth of 100m.

Supported analytes. This meter features ONE optical channel compatible to a broad range of optical pH and temperature sensors with SUB-connectors. The optical sensor of your choice must be purchased separately. Each optical sensor is automatically temperature compensated by the integrated fast Pt100 sensor head.

Stand-alone logging. Log your data (up to >1 year) without a connection to a PC with this stand-alone long-term logger. After the experiment, download the data with our included versatile Windows software for data processing. The integrated maintenance-free lithium battery is then recharged within <2 hours for the next deployment.

Huge data memory. This device comes with a built-in data memory of 4GB of industrial grade for ca. 40 million data points, offering virtually unlimited data memory even during long expeditions.

Shallow Water Oxygen Logger AquapHOx-L-O2

Broad range of optical O2 sensors
Operation up to 100 m depth
Stand-alone logging up to >1 year
Integrated rechargeable battery
Integrated fast Pt100 temp. sensor

The AquapHOx-L-O2 is an oxygen long-term logger for stand-alone shallow-water operation down to 100m water depth. It offers a great flexibility regarding application, as it can be used with the entire underwater oxygen sensor portfolio with SUB-connector. Simply exchange the sensor head, choose between different O2 sensor formats. These include oxygen sensor cap for long-time monitoring, fiber-optic micro- & minisensors for O2 profiling in sediments & over surface structures (corals, coralline algae, seagrass, kelp, etc.) at high spatial resolution, and ultra-trace oxygen sensor caps for measurements in oxygen minimum zones or de-oxygenation events.

Simultaneous pH monitoring can be realized by parallel deployment of the AquapHOx-L-pH logger. For deployments >100m depth, please refer to our deep-sea multi-analyte logger AquapHOx-LX with titanium housing.

Flexible-Analyte Deep Sea Logger

Broad range of O2, pH & temp. sensors
Operation up to 4000 m depth
Stand-alone logging up to >1 year
Integrated rechargeable battery
Integrated fast Pt100 temp. sensor

PyroScience stands for intriguing optical sensor technology: simple, compact & flexible sensor systems with expert customer support. With the new AquapHOx technology, we also offer a unique all-in-one flexible underwater solution to monitor the health of our oceans.

The AquapHOx-LX is a flexible multi-analyte long-term logger for stand-alone underwater operation down to 4000m water depth. It can be combined with a broad range of optical O2-, pH- or temperature sensors, offering unmatched flexibility for multiple applications with the same APHOX-LX device. These include e.g.

long-time O2 monitoring in ocean habitats
most sensitive trace O2 measurements in oxygen minimum zones or de-oxygenation events,
measurements of ocean pH on the total scale with neglectable impact of salinity,
contactless read-out of incubations chambers with integrated sensors and
profiling over surface structures, in sediments and along gradients at high spatial resolution.

Simply exchange the sensor head, choose between different analytes (pH, O2 or T) and various sensor formats.

The AquapHOx long-term logger is ideally suited for monitoring critical parameters and their dynamics in different ocean habitats, including open ocean, the deep sea and coastal habitats like coral reefs or coastal waters.

This all-in-one premium deep sea logger is also available as deep sea real-time data transmitter, and as shallow-water single analyte logger for O2 and pH.
